The longitudinal edges of the supporting-table 20' are formed with channels'29 andth'e edges of the sheet 13 are moved in these channels Recesses30 are provided in the channelled 20 in registration with the pilot-pins 26 so i i that the plunger 22, upon descending, will cause the pins26 to enter some ofthe holes 28 in the sheet'and the recesses 30,

grooved at 33.

the move mentof the sheet 13 being coordinated with the movements of the plunger to enable the pins to engage'the holes in the sheeton each descent of the plunger. enter the holes .in the sheet, the sheet is properly registered and is held stationary while the operation of aligning. the wire pulls and embedding them in the sheet is performed by mechanism carried by the plunger.

: Fixed to the underside of the plunger '22 by the screws 31 .is a .plate 32 --whichis Each of these grooves ac:

reciprocated on the parts of the table When the pins 26 -.Thedie members 34 are moved on their support 32 by means of'athrec-sided frame and connected parts. The frame consists of a lmigitudinal bar 37 secured to end bars 38 and 39. a The longitudinalbar 37 is connected to the-plate 32 by screws 40 which are fixed -in'the. plate 32.;and extend through slots 41 in the bar whereby a movable or sliding connection is established between the bar and the plate. Bolts '42 secure the bar 37 to the end bars 38 and 39 so that the three bars 37, 38 and 39 areshiftedas a unit, the ends'of the plate 32 being grooved at 43 to positively guide the bars 38 and 39 in'their sliding movement. r

'Threaded in the bar 37 is a plurality of rods 44, each of these rods being adapted to slidingly shift one of thedies 34. Each rod 44 is threaded at 45 in the bar 37 and is thus adjustable therethrough. A shoulder 46 is'formed on eachrod and the shoulder bears against the end of a bushing 47, the opposite end of which isheld against the face ofa die member 34,,a's shown n Fig. 6.

The inner end of the rod 44 is accommodated propen: position of adjustment once the proper setting thereof has been secured.

The die-shifting frame composed of the connected bars 37, 38 and 39 is slidingly shifted by means of cam surfaces, several of which are shown at 50 on members 51 secured at the opposite sides of the support 20. Cap screws 52 attach these cam members to the table20 as clearly shown in Figs. (3 and '8. The fixed cam surfaces 50 cooperate with cam surfaces 53 formed on the end of the bars 38 and 39. descends, the cam surfaces 53 will be brought into contact with the cam faces 50 on the fixed cammembers 51 whereby the frame composed of the and associated parts, will be shifted in the direction of thearrow 21, or in a direction at right angles to the movement of the plunger and parallel to the plane ofthe VVhen the plunger 22 bars 37, 38 and 39 "a." no

' per end the plunger 59 is provided ingly shifted in their grooves 33 againstthe pressure of the springs which surround rods 54 threaded into a bar attached to the edge of the plate 22. One end of each spring bears against a die member 34, the

o osite end of the salin b'earin a ainst a washer 8O impinging against the 's'houl' der 81 on the rod. The inner end of each of the rods 54 projects into a recess 56 formed in the die 34, the opposite end of each rod being threaded through the bar 55 and capable of being fixed in any position of adjustment by means of the lock nut 57.

Each of the die members 34 is provided with a recess 58 within which a plunger 59 is movable. At its lower end the plunger 59 is formed with a die portion which performs the functions of aligning or positioning the wire pull on each cap in the sheet 13 q and forming adepression 61 in the capto enable the cross-bar 16 of the pull to be easily raised by the finger-nail when the cap is to be lifted from its seat in a bottle neck. The plunger 59 is spring-pressed by the coilspring 62 which rests in a pocket provided in the upper end of the plunger. The normal or inoperative position of the plunger is shown inFig. 6; its fully compressed position being shown in Fig. 10. At its upwith a head 76 which, when the die member 34 has reached itseompletely descended position, abuts'aga-inst the under face 7660 of the plate 32 and holds the die portion 60 rigid relative to the die 34 causing the end, 7 3 of the die portion 60 to form the indentation 61- in sheet 13. 1

The bottom surface of each of the die members 34 is formed with raised die elements 71 and 72. Theseraised die elements are shaped to cover and embed the portions 115, 16 and 19 of the wire pull; That is to say, the die element 7 1. is substantially L shaped and serves to embed the cross bar 16 they pass and legs 15 in the top surface of the sheet 13. Similarly, the die elements 72 are of a shape to embed the ends 19 :of thepuil. The face of theidie element 71 is slightly inclined so that the legs 15 are more deeply embedded in the cap near the point where through it,than at the cross bar. This will be apparent from Fig 11 where the inclined position of the legs of the pull I when embedded is clearly shown.

Briefly, the operation of the apparatus is as follows g The sheet 13 in which a large numberof caps are defined, and in which the wire pulls 14 have been inserted as shown in Fig. 1,

is fed along on the support 20 beneath the plunger 22 by any suitable intermittent feed mechanism. The wire' pulls have their leg portions 15 and connecting cross-bar 16 extending upwardat an angle from the face of-the sheet as shown inFigs. 8 and 9. Durthe holes 28 formed at the side edges of the sheet 13, thus holding the sheet against any shifting movement while the alignment and embedding of the wire pulls takes place. As the plunger QQdescends, the cam surfaces 53 are brought into contact with the surfaces 50 on the fixed cam members 51 whereby the frame carrying the rods 44 is slidingly shifted in the direction indicated by the arrow'21. At the beginning of this shifting movement the plunger has partly descended and the parts are substantially in the position shown in Fig. 6. The rods 44 and bushings 47 slide all of the die members, 34 to the left of Fig. 6, this action causing the face70-on each ofthe die portions '85;

60 to be brought into forcible contact with one of the cross bars 16 of a wire pull whereby the wire pull is aligned or straightened preparatory to being embedded in the sheet 13. This action of the die portion 60 will of the sheet 13 along on its support 20 prior to reaching a point beneath the plunger 22 often causes the wire pulls to be misaligned or twisted relative to the sheet. In some cases the frictional contact of the parts 18 of the wire pulls with the face of the sup port 20 is sufiicient to project the parts 15 and 16 out of the sheet to a greater extent than is necessary. The action of the face 70 in forcibly contacting with the cross bar 16is such as to align and position the wire pull relative to the sheet to which it is at tached so that uniformity and proper-placement of the wire pull in each cap is assured. W After the face 70 of each die portion 60 has acted, by the sliding movement of the die members to align and position the wire pulls in the sheet 13, and the descent of plunger 22 continues, the embedding of the parts of the 'wire pull occurs. This enibedding operation is performed by the die elements 71 and 72 which embed the parts- 15, 16 and-19 of'the pulls in the upper face of the sheet. While the parts 15, 16 and 19 of the pulls are being embedded by the presand position this Wire" sure of the die portions 71' and 72, the depression 61 is being formed in the top face of the cap by the action'of the inclined lower end 73 of the die portion 60, as clearly shown inFig. 10. The plunger 22 is then raised and the sheet 13 is moved tobring the nextgroup of caps in the sheet below the;

plunger in readiness for its next descent." Since the under face of the sheet 131s hrmly pressed against the face of the table 20. by the pressure of the embedding dies. the

layer 90 maybe secured by an adhesive to the under faceof the cap to cover the parts 18 of the polls and incidentally close the minute holes formed in the-cap by the passage of parts of the pull through it. Such a layer 90 is preferably secured to t e under face ofthe sheet before the caps are stamped from it. lVhat I claim is i i N u l.
